1. add stamina bar that can affect your running and your aim (would be great if u just add it on veteran difficult)
2. if we have blade/knife make it can tore clothes and pants into rags
3. make it we can loot from refrigerator,drawer,etc
4. like poeple mention on above me: simple command on friend, like stay close, cover, spread, rest(so he can regain his health), exchange (so can trade his for better armor and weapon)
5. can makeshift rope from rags
6. can makeshift hut just using wood and rope, exemple you have 10 or 15 wood and 3 or 5 rope then combine all item to build makeshift hut
7. make it item that count as 1 item per slot will be stacked when i have several item on ground like wood or rice or canned beer or zuichin, etc. because when i have 40 zuichin to scroll down item most bottom feel so tiresome
8. make it we can craft, eat, drink from that coloum on left
